The NSX is like the poor man's exotic, and it will always be viewed as such. There are significantly cheaper cars out there that put down better peformance numbers. And for a flagship vehicle, it's almost invisible (how many average people know what an NSX is?)
I doubt that the NSX will incorporate much F1 technology, if any. Honda seems to be advertising itself these days on the basis of its advances in energy systems (ie hybrids and fuel efficiency) than touting its racing heritage.
